Infancy/Early Childhood (birth to 6 years) includes which typical milestone?

• A. Mastering calculus
• B. Potty training
• C. Learning to drive
• D. Becoming a senator

Answer: (B)

Potty training exemplifies a self-help milestone that emerges in infancy and early childhood as children gain greater independence in daily routines. It marks a child’s developing bladder and bowel control, readiness to follow simple instructions, and willingness to participate in personal care without constant adult help. This transition typically appears around ages 2 to 3, though it can vary, and is generally completed within the birth to 6-year period. The other activities listed—mastering calculus, learning to drive, and becoming a senator—occur much later in life and are associated with formal education, adolescence, or adulthood, not early childhood. So potty training best fits the typical milestones for this age range.
